Eclipse

 

Shortcuts:

 

type "syso", followed by CTRL + SPACE. Eclipse will magically fill out the full System.out.println() function call and place your cursor in between the parentheses

 

Eclipse Plugin:

 

— TM terminal (previously named TCF terminal)

Installed from Help -> Eclipse Marketplace

Type Ctrl + Alt + T 

 

System.out.println (“sysout” and Ctrl + Space)

When working with console applications, you’ll need to use System.out.println() for printing messages. But because this is so cumbersome, Eclipse has a quick shortcut for you: type “sysout” (without the quotes), then hit Ctrl + Space.

Search Entire Project (Ctrl + H)

When working on large codebases, it’s easy to forget where you declared certain classes, methods, or variables. Instead of wasting time combing through directories by hand, use the Search Entire Project prompt with the Ctrl + H shortcut.

the full list of shortcuts can be displayed from anywhere via Ctrl+Shift+L.

you are on Mac, then just press key: Command + Shift + L.

Enabling Assertions in Eclipse

In Eclipse, select "Run » Run Configurations..." from the menu bar. This will open up a dialog window. If you do not already have a run configuration for the current file, go ahead and create one. Otherwise, select the "Arguments" tab and enter -ea in the "VM Arguments" text box as follows:

Eclipse-Wide Settings

If you always want assertions enabled for any Java project you run in Eclipse, you have to change the settings for your installed JREs. Go to the Eclipse Preferences window (either "Window » Preferences" or "Eclipse » Preferences" from the menu bar). Open the "Java" submenu, and select "Installed JREs". You should see something similar to:

 

 

Decompile Java

 

Using jad:

$ ./jad -sjava BasicColor.class

 

JD-Eclipse

 

JD command line:

 

java -jar EnumLevel.class
